If ur tama mated with a friend on ur friend list no matter how many generation ago, and then U delete that friend, you can't see parents OR grandparents. But, if U didn't delete any friends, I don't know. ???. I mated with a tama on the 4th gen and it was on my friend list and I had 40 friends, so I had 2 delete a couple. I deleted that 1 and then, it wouldn't let me see my parents list!
